Use perigee surface as target surface in fitting
This MR includes the following changes:
- Use perigee surface at beamline as target surface in fitting algorithm
- Residual plot tools now plots residual/pull of fitted (perigee) parameter instead of parameters at each track state
- Add plotting script for looking at perigee parameter resolution
An example of perigee parameter resolution with 10 GeV/c muon at Generic detector and ATLAS B field could be found here:
